Abstract: An additive manufacturing method for a part includes forming a pillar by fusing metallic material to form a hollow body portion including a wall having an inner surface and an outer surface and fusing metallic material to form a cap portion extending from a distal end of the body portion. The method includes forming the pillar by fusing metallic material to form a distal portion supported on the cap portion, supporting at least a portion of the part by the pillar, and removing the pillar from the part.

Abstract: A method of manufacturing a hydraulic valve component using additive manufacturing includes laying successive layers to form a flow aperture for a hydraulic valve component, and creating a lattice or mesh structure that at least partially defines the flow aperture of the hydraulic valve component, or a feature that forms an undercut along a direction that is parallel to a flow direction of the flow aperture, or a flow aperture having a size varying along a circumferential direction of the valve component.

Abstract: A system for molding a non-pneumatic tire may include a lower mold portion including a lower face plate configured to provide a lower relief corresponding to a first side of the tire. The system may further include an upper mold portion configured to be coupled to the lower mold portion. The upper mold portion may include an upper face plate configured to provide an upper relief corresponding to a second side of the tire. The system may also include a plurality of mold inserts configured to be positioned between the lower and upper face plates. The mold inserts may include a shell portion at least partially enclosing a void configured to provide a cavity in the tire, and the shell portion of the mold inserts is configured to remain embedded in the tire upon removal of the tire from the lower and upper mold portions.

Abstract: A non-pneumatic tire may include a hub configured to be coupled to a machine, with the hub having a rotational axis about which the tire is configured to roll. The tire may also include a support structure including an inner circumferential portion associated with the hub and an outer circumferential portion radially spaced from the inner circumferential portion. The support structure may extend between opposed, axially-spaced side edges of the tire, and the support structure may include a plurality of cavities. The tire may also include a tread portion associated with the outer circumferential portion. The support structure may also include a plurality of layers of elastomeric material each having opposing faces lying in opposing planes substantially perpendicular to the rotational axis. At least some of the layers may include apertures corresponding to the cavities, and the layers may be chemically bonded to one another.
